Definitions

  • the present invention relates to a device to be included in a printing machine for retaining a master stencil sheet, and more particularly relates to a device for attaching and retaining the leading edge of a stencil master sheet along a generator of a printing drum incorporated in a printing machine.
  • Various currently known types of printing machine incorporate a printing drum device around which a stencil master sheet is wrapped for performing the printing process; typically, in the use of such a printing machine, ink for printing is supplied from the inside of the printing drum via a large number of small holes in its outer surface to the inner side of the stencil master sheet wrapped therearound, and passes (only) through the perforated portions of said stencil master sheet to the outer side of said sheet, so as to be imprinted on a printing sheet such as a paper sheet and so as to duplicate the pattern perforated on said stencil master sheet.
  • a device is required for securing one edge, typically the leading edge, of the stencil master sheet to the printing drum, typically along one of the generators thereof, in order securely to fix said stencil master sheet to the printing drum during the stencil printing process; and this securing or retaining device is required selectively to be actuatable to thus fix the edge of the master sheet to the printing drum, or to be actuatable to release said edge of said master sheet.
  • stencil master retaining devices have been proposed, and in particular the assignee company of the present patent application has proposed, in Japanese Patent Applications Ser. Nos.
  • a clamp type stencil master sheet retaining device in which a magnet plate is fitted generally along a generator of the printing drum, and a movable clamp plate is selectively either held away from said magnet plate or is allowed to be attracted against said magnet plate by the magnetic force thereof.
  • This type of stencil master retaining device is very adequate for use in the case that the leading edge of the stencil master is thickened and reinforced by a retainer reinforcement strip; however, in the case that the stencil master sheet is thin and is of the so called headless type in which its leading edge is not particularly differentiated from its main body and is not thickened or reinforced (and this is a type particularly suited to automatic operation, since such stencil master sheets can be cut successively from a long roll of stencil master), then the difficulty can arise that, when the clamp plate is raised away from the magnet plate to release the leading edge of said stencil master, said leading edge does not properly become separated from said magnet plate against which it was clamped, but remains attached thereto (and thereby to said printing drum) by the effect of static electricity or the like.
  • a stencil master sheet retaining device comprising: a magnet plate extending generally along a generator of said printing drum; a clamp plate, made of magnetically attractable material, which can be selectively positioned either to a position in which it lies against said magnet plate, or to a position in which it is removed away from said magnet plate; a removal strip which extends above said magnet plate generally between said magnet plate and said clamp plate; and a means for raising said removal strip away from said magnet plate, when said clamp plate is removed away from said magnet strip.
  • the clamp plate is positioned to be removed away from the magnet plate, and this causes the removal strip to be raised away from said magnet plate by the means for doing so, which positively and effectively lifts said leading edge of said stencil master sheet away from the magnet plate, thus breaking any undesirable residual engagement which might be otherwise provided between said leading edge and said magnet plate due to the action of static electricity or the like.
  • This ensures that the subsequent operation of removing and ejecting the stencil master sheet from the printing machine will be successful and will not be subverted by unplanned and undesirable adhesion of the stencil master sheet to the magnet plate.
  • this retaining device is well suited to use in an automatic type of stencil printing machine, and in one in which the stencil master used is thin and smooth, such as one in which said stencil master is made from thermally perforable stencil master material and is thermally perforated. And, further, this positive removal of the leading edge of the stencil master sheet away from its retained position along said generator of the printing drum by the removal strip does not involve any thickening requirement for said leading edge of said stencil master sheet, and thus the present invention is suitable for application to a stencil printing machine in which the stencil master sheet is of the so called headless type in which its leading edge is not particularly differentiated from its main body and is not thickened or reinforced, such as the type of stencil master sheet which is cut successively from a long roll of stencil master.
  • one end of said removal strip may be fixed with relation to said printing drum, and said removal strip, when said clamp strip is removed away from said magnet strip, may be raised away from said magnet strip by being put into compression. Further, said removal strip, when said clamp strip is removed away from said magnet strip, may be raised away from said magnet strip by being put into compression by its other end, which constitutes said raising means, being moved in the direction towards its said fixed end.
  • said removal strip from its said fixed end, may be passed over said magnet plate and around said axis, and its said other end may be fixed to said clamp plate.
  • the part of said clamp plate generally at said axis of rotation thereof, around which said removal strip is passed may be thickened, and, when said clamp plate is positioned to lie against said magnet strip, said removal strip may be pulled tight and held against said magnet strip between said clamp plate and said magnet strip.
  • FIG. 1 is a perspective view of essential portions of a drum type printing machine which incorporates the preferred embodiment of the master retaining device of the present invention
  • FIG. 2 is a transverse sectional view of the drum of said printing machine and of said preferred embodiment master retaining device, showing the leading edge of a stencil master just being started to be fed onto a mount of said retaining device for being gripped by a clamp plate and retained;
  • FIG. 3 is a section similar to that of FIG. 2, showing said leading edge of said stencil master in the position of having been fully fed onto said mount and being about to be clamped by said clamp plate;
  • FIG. 4 is another section similar to those of FIGS. 2 and 3, showing the apparatus in its operational condition of gripping said leading edge of said stencil master by said clamp plate;
  • FIG. 5 is another section similar to those of FIGS. 2 through 4, showing the apparatus in its operational condition, having released said leading edge of said stencil master from its gripped condition by said clamp plate of forcibly raising said leading edge away from the top surface of said mount by the arching of certain thin flexible strip members.
  • FIG. 1 is a perspective view of relevant portions of a drum type printing machine incorporating this preferred embodiment
  • FIGS. 2 through 5 are transverse sectional views therethrough, showing said preferred embodiment in various different operational states.
  • the reference numeral 1 denotes a cylindrical printing drum of a rotary stencil printing machine, and this printing drum 1 is supported, so as to be rotatable around its longitudinal axis with respect to a frame not shown of the printing machine, by three rollers 3 provided at each end of said drum 1, which support said end of said drum 1 via an annular guide and support ring 2 formed on each said end of said drum 1.
  • the drum 1 is formed as a hollow cylinder and has a large plurality of small holes formed through it for conducting printing ink during the printing process from its inner surface to its outer surface, but since this matter is not directly relevant to the present invention it will not be further discussed herein.
  • a master retaining mount 4 formed as a platform is mounted on the outer surface of the printing drum 1 and extends generally parallel to the generators of said drum 1.
  • the shape of this retaining mount 4 can be best seen in the sectional views thereof presented in FIGS. 2 through 5: it has an upper surface 5 which is generally formed as two plane surfaces 5a and 5b which would meet in a line parallel to the generators of the printing drum 1 and which are angled at an obtuse angle to one another, and also has a particular sloping face 12 joining between the plane surface 5a and the outer surface of the drum 1; this particular sloping face 12 is the trailing sloping face of the retaining mount 4 with respect to the preferential direction of rotation of the printing drum 1, which is indicated by an arrow in the figures.
  • the upper surface of the mount 4 is scooped out in the form of a generally cylindrical trough 50 which extends parallel to the generators of the printing drum 1 substantially from one end to the other of said drum 1.
  • this trough 50 At opposite ends of this trough 50 are provided bearing lugs 7a and 7b with mounting holes formed through them whose common axis is substantially coincidental with the central axis of the cylindrical trough 50, and, as shown in the drawings although it is not absolutely necessary for the present invention, the side edges of the trough 50 are rounded off to make them smooth, and in particular the side edge of said trough 50 on the side thereof towards the abovementioned sloping face 12 is so rounded off, as shown by the reference numeral 60 in the figures.
  • a strip shaped magnet plate 6 which extends in the direction of the generators of the printing drum 1 substantially entirely along the longitudinal direction of the retaining mount 4, from one end to the other of the printing drum 1, and the upper surface 6a of this magnet plate 6 is coplanar with this upper plane surface 5a of the mount 4.
  • This magnet plate 6 is a permanent magnet, such as a multipole magnet, and is formed of a material of suitable frictional and resilient characteristics, such as rubber magnetic material.
  • this magnet plate 11 embeddingly inlaid into the planar upper surface 5b of the retaining mount 4 on the leading side of the trough 50 there is provided another strip shaped magnet plate 11, which also extends in the direction of the generators of the printing drum 1, and the upper surface 11a of this magnet plate 11 is similarly coplanar with this upper plane surface 5b of the mount 4.
  • This magnet plate 11 also is a permanent magnet such as a multipole magnet, and may be similarly formed of a material with the frictional and resilient characteristics of material such as rubber magnetic material, although this is not essential.
  • a clamp plate 8 is formed as a long strip member and is made of a magnetically attractable material such as steel. Along a long edge of this clamp plate 8 there is integrally formed a substantially cylindrical and quite thin roller member 9, with the clamp plate 8 extending substantially radially outwards from this roller member 9, joining to it along one of its generators. From the opposite ends of this roller member 9 there extend mounting axle members 51a and 51b (see FIG. 1), and the somewhat shorter one 51a of these axle members is fitted into the mounting hole of the lug 7a, while the other axle member 51b which is the somewhat longer one thereof is fitted through the mounting hole of the other lug 7b and has a drive pinion 10 fixedly mounted on its end.
  • the clamp plate 8 and the integral roller member 9 are rotatably supported parallel to the generators of the printing drum 1 by the lugs 7a and 7b, with the roller member 9 held partly within and substantially coaxial with the trough 50, and with a certain gap, designated in the figures as 52, being left between the outer surface of the roller member 9 and the inner surface of the trough 50.
  • This gap 52 is sufficiently wide (in its extent in the radial direction of the trough 50) for a plurality of elastic strips 13 which will be discussed below to fit through it, between the outer surface of the roller member 9 and the inner surface of the trough 50.
  • the clamp plate 8 and the integrally formed roller member 9 can be selectively rotated, by turning and positioning the drive pinion 10 appropriately, either: to its fullest extent in the clockwise direction as seen in the figures to a clamp position as shown in FIG. 4 in which said clamp plate 8 rests and is pressed against the trailing magnet plate 6 (with the interposition of certain membranous elements therebetween as will be explained later) and is attracted by said magnet plate 6 and is thereby held in this clamp position; or to its fullest extent in the anticlockwise direction as seen in the figures to a release position as shown in FIGS.
  • the means provided for thus rotationally driving the clamp plate 8 and the roller member 9 by turning the drive pinion 10 includes a drive gear wheel which selectively meshes with the drive pinion 10 and various drive and control means, and is not shown in the present figures and will not be further discussed herein with regard to its structure but only with regard to the functions which it performs; if detail is required as to the structure of this drive means for the clamp plate 8 and so on, reference should be made to Japanese Patent Application Serial No. Sho. 57-207217 (1982), which has been published as Japanese Patent Publication Serial No. Sho. 59-96984 (1984).
  • the one ends 13d of a plurality (five in the shown preferred embodiment) of thin flexible strips 13 which are made of sheet material, as best seen in FIG. 1; only one of these strips 13 can be seen in the sectional views of FIGS. 2 through 5, because only this one of these strips 13 is sectioned by the plane of these figures.
  • the material for these thin strips 13 may exemplarily be polyester sheet with a thickness of 0.05 mm to 0.5 mm, or carbon fiber sheet.
  • Each of these strips 13 is fixed as extending in the direction peripheral to the printing drum 1, i.e. perpendicular to the generators thereof, and is extended, as shown in FIGS.
  • each of these flexible strips 13 is so arranged that, when the clamp plate 8 and the integral roller member 9 are rotated by turning the drive pinion 10 to the fullest extent in the clockwise direction as seen in the figures to their clamp position as explained above and as shown in FIG. 4 in which the clamp plate 8 is pressed against the trailing magnet plate 6 (with the interposition therebetween of certain membranous elements as will be explained later) and is attracted by said magnet plate 6 and thereby held in this clamp position, then said thin strip 13 is stretched substantially tight between its end portions 13a and 13d, so that its main portion 13c is pulled straight and tightly against the surface 6a of the magnet plate 6 and the coplanar surface 5a of the retaining mount 4.
  • FIG. 2 there is shown the beginning stage of the attachment of a sheet S of flexible master material to the outer surface of the printing drum 1.
  • the clamp plate 8 and the integral roller member 9 are positioned by turning of the drive pinion 10 to the fullest extent in the anticlockwise direction as seen in the figures to their release position as explained above in which the clamp plate 8 is pressed against the leading magnet plate 11 and is attracted by said magnet plate 11 and thereby held in this clamp position, and the thin strip 13 has a certain amount of slack in its extension, so that its main portion 13c arches upwards and away from the surface 6a of the magnet plate 6 and from the coplanar surface 5a of the retaining mount 4.
  • the leading edge of a sheet S of master sheet material is fed (by a feeding means, not shown in the figures, which will not be discussed herein with regard to its structure but only with regardf to its function) in the leftwards direction in the figure, so as to be approached to and to be brought above the upper surface 6a of the trailing magnet plate 6, with the interposition therebetween of the main portions 13c of the flexible strips 13, over which said leading edge of the sheet S of master material slides and on which it rests.
  • the printing drum 1 is rotated in the anticlockwise direction as seen in the figures, so as to wrap the master sheet S around said printing drum 1, in preparation for stencil printing; this process, and the stencil printing process which follows thereupon, will not be particularly described herein, and are not shown by any figures, because they are not directly relevant to the present invention.
  • the leading edge of the stencil master sheet S is brought to a position in which it is lifted up away from the surface 6a of the magnet plate 6 and away from the coplanar surface 5a of the retaining mount 4, whereby it is well prepared for the next stage in the operation of this printing machine (not particularly described herein) in which the printing drum 1 is rotated in the clockwise rotational direction and the stencil master sheet S as a whole is peeled away from said printing drum 1 and is detached, compressed, and discarded.
  • an important but not essential feature of the shown preferred embodiment of the present invention is the rounding off (shown by 60) of the side edge of the trough 50 on the side thereof towards the sloping face 12 of the mount 4, because this ensures that scratching and frictional damage on the strips 13 of flexible material is minimized, as they are pulled to and fro through the gap 52.
  • This is a useful specialization of the present invention.
  • the provision of the thin flexible strips 13 as a plurality of strips is not essential thereto.
  • Other possible modifications of the present invention could be conceived of. Therefore, although the present invention has been shown and described in terms of the preferred embodiment thereof, and with reference to the appended drawings, it should not be considered as being limited thereby, since many possible variations on the shown preferred embodiment are possible, without departing from the scope of the present invention; and likewise the presently appended drawings may contain various features which are not essential to the gist of the present invention.
